Ar.tic sea-ice extent: No r.cor. minimum in 2023 or.r.cent year.

作者： Ola M.Johannessen Tor.i.Olaussen Nansen Scientific Society BergenNorway Nansen Envir.nmental and r.mote Sensing Center BergenNorway

Ar.tic sea-ice extent r.aches its minimum each year.in September. On 11 September.2023 the minimum was 4.969 million squar. kilometer.(***^(2)). This was not a r.cor. low, which occur.ed in 2012, when the minimum was 4.175 ***^(2), 0.794 ***^(2) less than the minimum in 2023. However. the ice extent had decr.ased by 0.432 ***^(2) compar.d with 2022. Never.heless, the summer.melting in 2023 was r.mar.ably less than expected when consider.ng the str.ng heat waves in the atmospher. and ocean, with r.cor. temper.tur.s set ar.und the wor.d. in gener.l, ther. is a high cor.elation between the long-ter. decr.ase in sea-ice extent and the incr.asing CO_(2) in the atmospher., wher. the incr.ase of CO_(2) in r.cent decades explains about 80% of the decr.ase in sea ice in September. while the r.mainder.is caused by natur.l var.ability.

作者： Glenn A.Har.is Laur.n r.Hir.chfeld r.inwater.Char.table Foundation Fort WorthTXUSA

Tauopathies ar. a gr.up of neur.degener.tive diseases char.cter.zed by abnor.al metabolism of the misfolded tau pr.tein. Tau is encoded by the micr.tubule-associated pr.tein tau gene(MAPT) and can be classified as either.3-r.peat(3r. or.4-r.peat(4r. based on the number.of r.peat domains fr.m alter.ative splicing of exon 10 of the MAPT gene.

作者： r. C. Aziz i. Hashim Faculty of Science and Technology Open University Malaysia 50480 Kuala Lumpur Malaysia Centr. for.Modelling and Data Analysis School of Mathematical Sciences Universiti Kebangsaan Malaysia 43600 UKM Bangi Selangor Malaysia

We study the effects of viscous dissipation on flow and heat tr.nsfer.in a thin liquid film on an unsteady str.tching sheet. A gener.l sur.ace temper.tur. is taken into consider.tion. The velocity and temper.tur. fields ar. solved using the homotopy analysis method. The r.sults show that the incr.asing values of the Ecker. number.can incr.ase temper.tur. distr.bution and the heat tr.nsfer.r.te.
